At present, anthracite coal can be used for gas generators, but the key point is to use anthracite coal that cannot be bonded, because if the bonding property is relatively strong, agglomeration will easily occur when the coal enters the furnace. Therefore, when selecting coal, you should choose anthracite coal with relatively weak cohesion, or other coal types such as bituminous coal, coke lean coal, etc.

The industry continues to make new progress. As development needs continue to increase, the use of two-stage equipment derived from single-stage equipment has significant effects. double sectiongas generatorSince the material layer in the retort section and gasification section in the furnace is 6-8 meters, if the coal particle size is very different, on the one hand, it will reduce the gap between the bed and increase the resistance in the furnace, resulting in a decrease in gasification intensity, a decrease in output, and an increase in the carbon content of the ash; on the other hand, it is impossible to ensure that the coal is evenly and fully retorted, affecting the gasification effect of the two-stage furnace.

In recent years, with the development of science and technology and combined with actual production conditions, equipment has been widely used in industrial heating. Its energy-saving and environmental protection effects, low cost, and heating performance have been applied in the industry. Gas generators are developing in the direction of miniaturization, simplification, environmental protection and low production costs.
